* own the array.
|
|
*
|
|
* As above, it is legal to add null elements to the array. Note also
|
|
* that null elements can be created as a side effect of
|
|
* insertElementAt(). Conversely, if insertElementAt() is never used,
|
|
* and null elements are never explicitly added to the array, then it
|
|
* is guaranteed that queryElementAt() will never return a null value.
|
|
*
|
|
* Any of these methods may throw NS_ERROR_OUT_OF_MEMORY when the
|
|
* array must grow to complete the call, but the allocation fails.
